Default Re: Q-jet experts , couple questions

Holley simpler to tune? If you call up Mike Beachy and get the hanger adjusting tool he makes, you can tune the carb with simply changing the hanger once you get close with metering rods and jets. I dont see how you can get any simpler than that?

Power? I have been on at least 6 different dynos. A 800 to 850 Holley loses power on our SSers every time. That includes the expensive flowed boosters and all. The only carb that has ever out HPed the Q-jet is the 1150 with all the max tuned flow boosters and venturi. That was only 7HP.

Why do we use the Holley then? For measurements only with the Super Flow air bonnet. It screws with the vent tubes and the secondary air horn. We have found to relocate the air flow mechanism and relocate it as far away from the carb as possible, then making a custom Q-jet carb bonnet helps. The secondary air horn still doesnt like it.
